SEATTLE -- For nearly 10 minutes Friday, Padres catcher Michael Barrett made throws to second base and third base in an empty Safeco Field.

But this was no ordinary pregame drill for Barrett, who has been on the 15-day disabled list since April 8 with a sprained ulnar collateral ligament in his right elbow.

For Barrett, it might have been the final hurdle to clear before he's able to get on track to returning to the Major Leagues.

"It felt good," Barrett said. "There was no tingling."

If Barrett feels no effects from Friday's workout, the team will send him out on a Minor League rehabilitation assignment to Triple-A Portland, possibly as soon as Sunday.

"Mike is doing great. We'll see how he feels tomorrow after coming out of today," manager Bud Black said.

"He feels confident. He's been hitting, he's been running and he's been catching in the bullpen. Position-wise he's fine. Physically he had to make sure the arm was where he needed to be."

Black said Barrett would likely play in a minimum of five games with Portland before he would be considered to be recalled.

Barrett suffered the injury in a game at San Francisco on April 7. A subsequent MRI exam on his elbow revealed a sprained ligament. The initial prognosis was anywhere from two weeks to two months.
